Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 4 generators on 32 points:

(2,6,8,12)(3,9)(7,14,15,10)(11,16)(17,18,21,24)(19,25,26,32)(20,28,29,23)(22,30,31,27);(1,2,4,12,5,8,13,6)(3,10,11,7,9,14,16,15)(19,26)(22,31)(25,32)(27,30);(17,19,20,27,21,26,29,30)(18,22,23,25,24,31,28,32);(1,3,4,11,5,9,13,16)(2,7,6,10,8,15,12,14)
